Technical Tools

EngineeringDevops Engineer

Take ownership of the platform engineering function at an ambitious, early-stage AI infrastructure startup building next-generation inference solutions for open-source models. As a key engineering hire, you will shape the systems and services that make the platform accessible, reliable, and scalable for customers. Your scope will span full-stack development, backend services, Kubernetes infrastructure, customer onboarding, and compute orchestration. Working closely with the technical co-founder, you will have significant autonomy over architecture, tooling, and implementation decisions. This opportunity is ideal for a hands-on engineer who thrives in fast-moving startup environments and wants to make foundational technical decisions. You will also have the opportunity to contribute to a high-impact AI infrastructure platform while participating in its long-term growth through equity.

Own the platform engineering function end to end, covering the user interface, backend services, and underlying infrastructure.
Build, deploy, and operate backend services and Kubernetes-based platform infrastructure to support reliable, scalable customer experiences.
Design and implement customer onboarding workflows, virtual machine provisioning and onboarding systems, and fraud detection capabilities.
Make independent decisions on system architecture, technology selection, tooling, and vendors within agreed business and technical constraints.
Translate high-level objectives into practical engineering plans, deliver results, and communicate technical approaches and outcomes clearly to the team.
Ensure the platform remains usable, reliable, and scalable as customer needs and infrastructure demands evolve.
Manage expensive compute resources responsibly, balancing performance, reliability, operational complexity, and cost.
Collaborate closely with technical leadership to establish priorities and build the platform from its foundations.
